ww- Q IMPROVEMENT IN COMBINED GORN-PLANTER AND CULTIVATOR.

The Schedulereferred to in'these Letters Patent and making part of thesame.

To all 'whom it may. concern:

Be it known that we, M. J. KAVANAGH, of Joliet,

in the county of Will, and M. GREGG, of Chicago,`

in the county of Cook, and State of Illinois, have invented an improvedCombined Corn-Planter and Cul- .tivator; and we do hereby declare thatthe following proved corn-planter and cultivator.

The present invention relates to an improvement in that class ofcorn-planters and cultivators .which is arranged to convey the seed froma hollow hub to the ground by means of hollow spokes; and

Its nature consists in the novel construction of the parts for droppingthe seed, and the manner of adjusting the shovels, either to mark outthe ground and cover the seed, or cultivate the crop, as hereinafterfully shown.

F represents the axle-tree, E the hollow hubs of the wheels, and A theframe which supports the shovels and sides upon the said axle F.

1) represents hollow spokes, which are placed inside of tires O, of.suitable sizes to plant four hills at each revolution of the wheels.

The hollow spokes communicate with hollow-hubs E E, whichare suppliedwith seed-corn by means of removable screw-plugs 2, iig. 1, tapped intothem, and they are so mortised through, near theirouter ends, as toreceive ydropping-slides G, figs. 1 and 6, which are provided withchambers X,i'or receiving seed, and carrying it from the hollow spokes,and dropping it on the ground.

These dropping-slides are so operated upon by springs-V,'attached tothehubs and bearing onthev ends of the slides, as to carry the chambersthrough the hollow spokes, ,and they are carried back into the spokes bymeans of the following devices:

Cams H are pivoted at 3,1ig. 1, to springsJ, attached to eceentrics N,which are fastened to the axle F, and made to rotate with it. rlhesecams are provided with grooves a 4 5 in their faces, in which pins 6,figs. 3 and 6, fixed to spokes D, operate; andas the springs J, bymeans' of the eccentrics N, force the cams H outward, Awhile the groove4, iig. 3, are running on the pins, said cams bear against inclined lugsZ, projecting out from the dropping-slides, igs. l and 4, and draw saidslides into the hollow spokes far enough for the chambers X lt0 lillwith corn, the springs J` having previously forced the chambers out ofthe hollow spokes.

As the eccentrics N carry the dropping-slides back toward the .hubs E,the .pins -6 travel through the.

grooves 5, and then through grooves a, preparatory to another outwardmovement. Y

In order to insure this movement of the cams H, inclined lug-plates L Lare attached to the spokes, and so arranged that the cams will strikeagainst them, and insure such a movement of theirtapering ends as willdirect the pins from the grooves 4 to grooves a.

-The cultivating, marking, and covering-devices vconsist of twohorizontal bars P P, which are pivoted to the ont and rear end of theframe A, and which support shovel-standards Q Q Q Q, braced by rods W.

These beams are adjusted relative to the rows to be marked, covered, ortilled, by means of curved guides 0 O O O, iig. l, which are put throughthe beams P, and through curved slots formed in guide-plates 'l T,

which are attached to both ends of. said frame' A, the

curved guides O being held in place by means of n'uts S S, fitting theupper and lower sides of the guide.

plates.

It will be seen from this that the chopping is ar ranged to operateautomatically, and drop the corn in 'check-rows, and that the shovelsare adjusted to the various purposes set forth, by simply loosening thenuts S S, and moving the curved guides O O O O in the slots formed inthe plates l T.

. Having thus described ourinvention,

What we claim, and desire to secure by Letters Patent of the UnitedStates, lis-- l. The combination of the grooved cams AH', hollow spokesD, hollow hubs E, dropping-slide G, provided with chambers X, and lugsZ, eccentrics N, and springs J V, as and for the purpose set forth.

2. The combination of the beams P, standards Q, and slotted plates T, asand for the purposeset forth.
